SPECIFICATION forming part of Letters Patent No. 339,761, dated April13,1886.

Application filed February 28, 1885. Serial No. 157,388. (No model.

To all whom it may concern:

Be it known that we, LEWELL J. GILMAN, CHARLES W. Fnos'r, and CHARLES H.FOSTER, of Santa Rosa, Sonoma county, State of California, have inventedan Improvement in Harvesters; and we hereby declare the following to beafull, clear, and exact description of the same. 7

Our invention relates to that class of agricultural machines known,generally, as barvesters, and in some localities as headers; and ourinvention consists in the novel construction and mounting of thedraper-frame or platform and its connection with the main frame,wherebyit may be kept always level for any out, high or low, its limits ofmotion defined and regulated, and the whole frame evenly balanced; inthe novel power-transmitting connections, by which the work of themachine is divided between the two wheels in substantially equalproportions,- in the novel manner of adjusting the reel and in theinclination of its cross-bars; and, finally, in the means by which thespeed of the reel and the draper is regulated, all of which we shallhereinafter fully explain.

The general object of our invention is to provide an easy-working andreadily-handled header adapted to do its work without waste of materialor loss of power.

Referring to the accompanying drawings, Figure 1 is a perspective viewofour harvester. Fig. 2 is aplan showing the power-transmitting devices.Fig. 3 is a vertical cross-section of the reel, showing the inclinedbars V. Fig. 4 is a detail showing the crank-shaft U, for adjusting thereel.

A is theframe-work, supported upon wheels B,which are mounted in thesides of the frame and as nearly central as possible, whereby said frameis nicely balanced. Hinged to the rear of the frame is the pushbeam 0,having the steering-wheel c, the platform a, and the vertical rack 0 asusual.

D is the main operating-lever, by which the frame A is inclined. Thislever is connected with the frame at its forward portion, and is pivotedin a slotted standard, d, on its rear portion, and thence, extendingbackwardly, engages with the vertical rack E is the draper-frame orplatform, and F is the draper.

G isthe sickle-bar, and sickle. v

In the ordinary machines the diaper-frame forms a portion of the frontof the main frame, and consequently when said frame is inclined by theoperation of the lever the draper-fra1ne is inclined also, and the headswhich are cut by the sickle have atendency to fall forward again fromthe draper or backward over it. In our machine we have a transversepivotshafr, H, extending across the front of the main frame. Upon thisshaft the diaper-frame is hinged or pivoted,whereby it is adapted tohave a rocking movement independent of and adapted to counteract therocking of the main frame.

Projecting rearwardly from the ends of the draper-frame are side arms,6, which extend to the line of the pivot-axis of the main frame. Fromthe ends of these arms ext-end uprights 6, connected by the cross-bar 6above the wheels. Projecting rearwardly from the center of thiscross-bar is a limiting-arm, I, pivoted to said cross-bar and securedwithin a slotted standard, J, on the forward portion or cross-bar of thepush-beam.

g is the reciprocating The connection between the arm I and the.

standard J is an adjustable one, and consists of a series of holes, i,in the arm, and a se ries,j, in the standard, through which a removablepin or bolt, K, passes, whereby the lever may be shortened horizontallyand its point of adjustment varied vertically. The effect of thisconstruction is as follows: \Vhen the operating-lever is moved, the rearof the main frame A and the forward end of the push-beam are depressedor elevated, which movement, through the various connections, effectsthe reverse in the rear of the draperframe, and raises or lowers it,thus exactly counteracting the inclination of the main frame, wherebythe said frame is kept perfectly level, whether for a high or a low cut,and none of the grain is lost. ment of the arm 1 the limit of motionthrough which the draper-frame passes is defined, so that it may be madeto out very high, or be moved down low enough to pass immediately 5 Bythe adjust- 9 over the ground. lhe main frame being nicely balanced onits wheels and the draperframe being pivoted on a balance and operatedfrom a rear extension lying in the vertical plane of the pivotal axis ofthe main frame, the whole machine can be handled very easily.

In ordinary machines but one wheel is made to do the driving. Thiscauses great wear and strain upon the machine. Our machine is arrangedso that both wheels shall have about an equal portion of work toperform. The left-hand wheel is provided with a gear, Z, upon its axle,which meshes with the pinion z upon a counter shaft, L. This shaftcarries on its forward end a crank-wheel, Z, to which is connected apitman, Z, the other end of which joins the rear end of acentrally-pivoted lever, l, which operates the sickle'g.' Upon the shaftL is also a beveled pinion, m, which meshes with a beveled pinionfm, ona counter-shaft, M, the other end of which carries a cone-pulley, n.From this cone-pulley a belt, N, extends to a cone-pulley, n, on the endof the reel-shaft. It will be observed that the left-hand wheel hastherefore the working of the sickle and the reel.

On the axle of the right-hand wheel is a gear, 0, which meshes with apinion, 0, on a counter-shaft, P, which carries a chain-pulley, p, fromwhich a chain, Q, extends to a chain-pulley, g, on a counter-shaft, q.Upon this-same shaft is a cone-pulley, a", from which a belt, R, extendstoa cone-pulley, r, on the upper drum of the draper in the spout S. Thiswork of driving the draper is considered as about equivalent to the workwhich the other wheel has to perform.

'1 is the reel, which is mounted in the forward end of leverst, pivotedon the standards t, extending upwardly from the draper-frame, and havingtheir rear ends connected by links t with cranks u on a rock-shaft, U,which is journaled in bearings on the cross-bar e center of this shafthas a crank, u, by which it is rocked or oscillated. By operating thecrank the reel can be adjusted nearer to or farther from the ground, asmay be desired, and in order to hold it in theposition to which it isadjusted we have the arm or lever 11. connected with the crank u,andprovided with a series of notches, u on the under surface of its rearend, whereby it may engage with a cross-bolt, J, in the top of theslotted standard J on the cross-head of the push-beam,and thus hold theparts.

The cross slats or bars V of the reel, instead of being set in radialplanes,as is usually done, are set at a slight angle therewith, so thatinstead of coming with the fiat surface against the grain they workunder it with an inclined edge, thereby lifting it better upon thedraper.

It will be observed that the pulleys by which the reel is driven arecone-pulleys. The object of this .is that by moving or shifting the belttoone side or another by suitable means the reel may be driven at agreater or less speed. When the grain is light and stands the draper arealso cone-pulleys.

The

upright, the reel requires to be driven at a slow rate of speed, as allthat isnecessary is, that it shallinclinethe grain backwardly over thedraper; but when the grain is more or less down the reel requires to bedrivenvery rapidly, as well as to be lowered, whereby the grain isthrown backward onto the draper. For a similar reason the pulleys whichdrive When the grain is sparse and dry, the draper can be.

driven at a slow rate of speed, and thus save wear and tear upon it, andwhen the grain is heavy and thick it requires to be driven at a highrate of speed for the purpose of preventing it from clogging.

Having thus described our invention, what I r we claim as new, anddesire to secure by Letters Patent, is

In a harvester, the wheeled mainframe A, the. push-beam G, hinged toits rear, and havingv standard J on its forward end, and theoperating-lever D, by which the frame is inclined,in combination withthe draper-frame pressed or elevated the front of the draperframeislowered or raised to keep said draperframe on a level, substantially asherein def scribed.
